Welding strip for connecting ladders, 0.15 x 27 mm (20.25) m, nickel – unpacked

Pre-formed pure nickel strip for 18650-2P battery packs – with embossed markings, pitch 20.25 mm (0.15 mm × 27 mm × 1 m)
Are you building a premium 2P battery pack (parallel pair of cells) and looking for a material that offers lightning-fast assembly and zero energy loss? This moulded pure nickel strip (Pure Nickel Strip), with a thickness of 0.15 mm, a total width of 27 mm and a length of 1 metre, sets the professional standard for spot welding 18650-2P batteries.

Thanks to factory-cut notches with a precise centre-to-centre spacing of 20.25 mm, the strip fits perfectly onto cells mounted in standard plastic spacers. Unlike standard steel sheets, this strip is made from pure nickel, ensuring minimal internal resistance, maximum current-carrying capacity and absolute resistance to corrosion.


Key advantages: - Premium pure nickel: Guarantees superior electrical conductivity. The strip does not heat up under high loads, thereby protecting the cells’ chemistry from degradation. Furthermore, it will never rust – the connections retain 100 per cent of their properties even after years of operation in damp conditions.
- Special 2P design with a pitch of 20.25 mm: The cut-outs correspond exactly to the spacing of standard plastic grids for 18650 cells. You can connect a pair of cells in parallel in a single step, without the need for complicated cutting or measuring.
- The perfect balance in thickness (0.15 mm): The 0.15 mm thickness offers excellent current-carrying capacity for the vast majority of applications, whilst remaining perfectly flexible. A major advantage is that it can be reliably welded even using standard hobby and portable spot welders.
- Unrivalled solderability: Do you need to connect balance wires from the BMS to the interconnected cells? Tin adheres to pure nickel instantly and effortlessly – there’s no need to use aggressive fluxes or heat the joints for long periods.
